Royce channels Ok 1 has like nothing... 18 which is VCC is at 6.00V DC..... Pin Name Description 1 P4 Programmable input 4 2 P5 Programmable input 5 3 P6 Programmable input 6 4 F in VCO Frequency Input 5 RI Referency oscillator Input 6 RO Referency oscillator Output 13...

Next to nothing (see post below) pin 18 is carrying the voltage on this particular pll.. Usually they say tie one to another, pull to ground, cut trace ect.. this is weird because I dont know if they want both 5&6 tied to 7.2v or if tieing 5 and 6 with 2 different switches to 7.2 makes the...

Hi, My royce has a M58473P PLL in it. According to documentation I have found it says Take pins 6 and 5 of PLL1 high (7.27v) for more frequencys. I dont understand what they are referring to, and what the outcome (Gain in channels would be) If I were looking at pin 5 and 6 (I found a...

OFFICIAL MOD FOR THIS ROYCE Well time to contribute back to the forum... My uncle sent me 28 editions of this cb repair manual he purchased long ago dating back to the 80's.. I found this royce in there and figured I would share.. If anyone knows how to do the channel mod they list plz...

now I hijacked my own thread LOL.. back tomy question yet still relating to the 510.. if I do set the deakey to 2w for an amp.. Would I notice a big drop in quality barefoot, Or would I actually benefit from the aditional swing? 2-10 or so.. vs 4-10 or so

Yet from ANOTHER site... 1.Cut D14 Audio Limiter. 2.Tune L6 and L5 for max swing. So this is really unusual.. Yet another 1. Locate the 2.7 ohm resistor in front of the final bias resistor(15 Ohm w/RF bead) and change it to a .47 Ohm. (DO NOT change the 15 Ohm resistor!!) 2...

Well as not usually the case appearently ALL over the net its WRONG Power Tweek and Modulation There are 2 ways that I found to work. 1) Cut or remove D14 which is the modulation limiter. Re-tune L4, L5, L6, L9 for maximum RF forward output. If the modulation is to much, do it...

YOU DA MAN!! I will be opening that 510 tonight to make sure I didnt do nothing to the other coil... You would happen to know anything about Royce 680's? Would ya?

THANK U...thats the coil i am referring 2. I have a stock 510, and the one I modded and there is a noticable difference, and its not all overmodulated and crappy sounding.. Some said there is no way its barefoot or modded that I was indeed stepping on ppl with amps!!

Well USUALLY I wont clip, However with the 510 I want it as loud (distored if you will) as it can possibly go.. As far as the coils go, Thats how you get the max power by spreading them.. Even without clipping, I usually spread the coils, and turn the pots.. dependign on what the sites say..But...

I dont know how many 510's you have personally delt with, and I am far from professional with cb's, However clipping and spreading the coil has made a HUGE difference both on a meter and in real world applications.. I am aware a 2 pill would make the world difference with it, however wouldnt the...

Well again thats yet another reason I asked because I am a little under 2w and people say its blowing smoke, and its sounding good.. I wanted to know if going a bit higher would make it like above and beyond, yet clean!.... I noticed today I had problems communicating home to the base with my...

Well I didnt realize my thread was indeed hijacked and dont mind, as all knowlege relating to the issue does help.. I was a little confused which is why I asked. My main point was indeed to make my radio the loudest without overmodulating the crap out of it whereas I hear some.. I talk to wife...

Hey welcome, So what are you referring to? you mean you like less deadkey? and more swing? sorry for not understanding.. I am now to cb's again.. (5year vacation from them) and getting deeper into how they work, so I can tweak them 100% to the best of their ability while still sounding crystal...

Everyone info is valuable, As I am still trying to grasp the concept of deadkey/swing. Although I got a good idea how to set it, all realitive info is awsome :)..... Everyone has their own opinion

Thanks for the post.. Very good insight and describing personal hands on situations with different types of equipment Yet another question of debate.. To clip or not to... Shitty little radio's like the 510 I'll clip to get the max out of them, BUT if I am running a linear, I'd rather leave the...

You can say that again Nice way to put it. I am guessing myself I prefer having clean clear modulation. Mainly started the hobbie to talk to wife from car when I am out, So of course I want to be heard loud but clear.. I dont know how many watts will make you "Bleed over" and wont talk when...

Thanks... again I will be purchasing that cable today.. A final note, on car cb's where there are coils and slugs, how do you set them? I know how to tune to max output, as well as clip to overide modulation limitation. I am currently running my 510 barefoot... So how would I adjust the...

WHOA! look at what I have done LOL...GOOD INFO... Not Complaing, But being this is originally my thread, set the math aside, what should I set the deadkey at vs swing for everyday use and good sounding radio..my my my... When dealing with clipping and peeking a car rig that doesnt have a...

LOL.. I replied to this earlier but the storm knocked out the power as I hit send. I wasnt meaning it as I didnt like the info.. It was very interesting, at the same time I am new and didnt understand this info in noobie english :).. I've printed this info for learning literature in future...
